2. Design
Description
Heating with pellets with the use of the ATMOS A45 pellet burner has a lot in common with natural gas
or oil heating. However, there is a difference that burning of pellets produces a certain quantity of ashes that
must be removed from the burner and boiler in an interval to avoid impairment of efficiency or affecting the
functionality of the burner.
The ATMOS A45 pellet burner is supplied with automatic fuel ignition as standard. The assembly of the
burner, external conveyor and fuel bin work completely automatically during operation and is controlled by an
electronic control unit with the use of a flame sensor (photocell). In the burner body the fuel and combustion
air are supplied in such a way to ensure maximum efficiency and environment-friendliness of fuel burning.
Only high-quality pellets with the diameter of 6 to 8 mm and length of 5 to 25 mm should be fed into
the burner. Pellets made of soft wood without bark, called white pellets, are considered as high quality
pellets.
Ashes are normally removed from the burner through the open door once every 7 to 30 days as necessary.
It is recommended to thoroughly clean the inner parts of the burner once a year; for this operation the burner
should be removed from the boiler. For ideal cleaning of the combustion chamber (pot) of the burner you can
use a special vacuum cleaner or a poker.
The burner consists of the following parts:
CAUTION - For the A45 burner DRA50 external shaft conveyors with the length of 1,7, 2,5,
4 and 5m with the diameter of 80 mm and also DA50 external shaftless conveyors with the
lenght of 1,7 m with diameter of 90 mm are designed. If you use DA50 conveyors, there is nec-
esary to change the setup of the burner. Specifically the T4 and T6 parameters (T1 - increase,
T4 - increase, T6 - reduce, see table on the page 33).

4. Safety, burner installation and commissioning
Safety and connection of the burner to the boiler
WARNING - Before starting the burner you must carefully read all the provisions of this
manual. At the same time you must observe all general safety regulations for work with
heating equipment resulting from the valid legislation.
• The premises where the equipment will be installed must comply with all fire protection regula-
tions in accordance with valid standards and laws.
• The equipment must be positioned in such a way to ensure access for cleaning and removal of
ashes not only from the burner, but also from the boiler, flue gas duct and chimney.
• The burner must be installed to the boiler over a sealing cord, soft Sibral sealing or another insu-
lation and sealing material to prevent flue gas from escaping along the burner to the boiler room.
Under one of the nuts with the use of which the burner is attached to the boiler a SPECIAL
SHEET-METAL PART - END SWITCH STOP must be positioned. It is used to compress the
end switch that monitors the proper position of the burner on the boiler. This protective device
must not be omitted in any case as it is directly related to fire safety.
• The connection between the burner and the boiler must be properly tightened to prevent flue gas
from escaping to the boiler room.
• During the installation you must make sure that the pellets can freely fall through the hose to the
burner. The connections between the hose, burner and conveyor must also be properly tightened.
Design and technical measures for increasing safety
• The ignition and combustion process is controlled by the electronic control unit by means of the
flame sensor - photocell. If the sensor does not sufficiently see the flame during operation, it will
automatically put the burner out of operation.
• The electronic control unit senses the speed of the burner fan and at any problems of the fan it
automatically puts the burner out of operation.
• On the burner frame there is an end switch and end switch stop that does not make it possible
to start to burner if the burner is not properly fixed to the boiler (e.g. after cleaning of the burner).
If during normal operation of the burner the end switch gets disconnected, the burner will be
automatically put out of operation. If at the start after two attempts with the fuel supply and one
attempt without the fuel supply the pellets are not ignited, the burner will be automatically put out
of operation.
• If during normal operation of the burner the fuel bin runs out of pellets, the burner will try a new
start and subsequently will be put out of operation. After replenishing pellets in the fuel bin and
drawing pellets to the conveyor you can start the burner by merely turning off and on the burner
switch on the boiler panel.
• The flexible transparent hose between the burner and external conveyor is made of special ma-
terial that melts at high temperatures and the hose will change to a spring that will separate the
burner from the fuel bin.

Operation and Maintenance Manual - GB
GB
www.atmos.cz GB-11
• The safety thermostat - located on the fuel supply pipe of the burner, will shut down the burner
if its temperature is higher than 95 °C. Thus, it protects the burner from return ignition of pellets
in the conveyor and at the same time from operation with clogged flue gas exhaust from the boiler
(e.g. in case of a failure to remove dust from the boiler, flue gas duct and chimney). The safety
thermostat will also put the burner out of operation in case the hose between the burner and con-
veyor gets perforated to prevent flue gas from escaping to the boiler room.
INFO - After any shutdown of the burner when an error message (ALARM) appears on
the display it is necessary to immediately find the cause and remove it. After removing the
cause of the error you can start the burner by merely turning off and on the burner switch,
which is located on the boiler panel.
Basic dimensions of the opening for installation of the burner in a boiler
In the case of the D30P, D31P, P31 and D45P boil-
ers the burner is fastened to the frame of the boiler

5. Type of environment and location of the boiler with the
burner in the boiler room
Boilers with a pellet burner may be used in the AA5/AB5 basic environment in accordance with
the ČSN3320001 standard. Boilers must be installed in a boiler room with guaranteed sufficient sup-
ply of combustion air. It is unacceptable
to locate boilers on residential premises
(incl. corridors). The cross-section of the
opening for supply of combustion air to
the boiler room must be at least 350 cm2
for boilers with an output of 5 - 45 kW.

2. Flue gas duct
3. Boiler
4. A45 burner
5. External conveyor
6. Bin (500 l)
6. Chimneyn
A boiler with a burner must always be connected to the chimney vent with consent of the re-
sponsible chimney maintenance company. The chimney vent must always produce sufficient draught
and exhaust flue gas to the free atmosphere in virtually all operation conditions. For proper function
of boiler the separate chimney vent must be properly dimensioned as the combustion, output and
service life of the boiler depends on its draught. The draught of a boiler directly depends on its cross-
-section, height and roughness of the inner wall. No other device may be connected to the chimney to
which a boiler is connected. The diameter of the chimney must not be smaller than the outlet on the
boiler (min. 150 mm). The chimney draught must achieve prescribed values (see the technical specifi-
cations in the boiler manual). However, the boiler must not be excessively high so as not to reduce the
efficiency of the boiler and not to disturb its combustion (tear the flame). In case of too strong draught
install a throttling flap or draught reducer in the flue gas duct between the boiler and the chimney.
Guideline values of dimensions of the chimney cross-section:
20 x 20 cm height 7 m
Ø 20 cm height 8 m
15x15cm height 11 m
Ø 16 cm height 12 m
The exact determination of chimney dimensions is defined by the ČSN 73 4201 standard.
The prescribed chimney draught is specified in the “Technical data” chapter of the manual
of the particular boiler.
CAUTION - The draught of the chimney during operation must ensure the minimum vacu-
um of 2 Pa in the combustion chamber of the boiler.

Operation and Maintenance Manual - GB
7. Flue gas duct of the boiler
The flue gas duct from the boiler must lead to the
chimney vent. If the boiler cannot be connected directly
to the chimney vent, the corresponding flue gas duct
adapter must be as short as possible with regard to the
particular conditions, but not longer than 1 m, without
additional heating surface and it must rise towards the
chimney. Flue gas ducts must be mechanically strong
and leak-proof for flue gas and cleanable inside. Flue gas
ducts must not lead through other owners‘ residential or
commercial units. The inner cross-section of the flue gas
duct must not be larger than the inner cross-section of
the smoke uptake and must not get narrower towards the
chimney. The use of smoke elbows is not suitable. De-
signs of passages of flue gas ducts through structures of
flammable materials are defined in Annexes 2 and 3 of
ČSN 061008 and are mainly suitable for mobile units,
wooden huts, etc.
1. Flue gas thermometer
2. Cleaning opening
3. Throttling flap (draught reducer)
INFO - In case of too strong draught of the chimney install a throttling flap /3/ or a draught
reducer in the flue gas duct, see the ATMOS price list.
8. Fire protection within the installation and use of heat appliances
Extract from ČSN 061008 - Fire safety of local appliances and sources of heat
Safe distances
On installation of an appliance the safe distance from building materials must be maintained, at
least 200 mm. This distance is valid for boilers and flue gas ducts located near flammable materials of
the B, C1 and C2 flammability class (the flammability class is specified in tab. no. 1). The safety distan-
ce (200 mm) must be doubled if boilers and flue gas ducts are located near flammable materials of the
C3 class (see tab. no.1). The safety distance must be doubled if the flammability class of flammable
material is not evidenced. The safety distance may be reduced to a half (100 mm) if you use a non-flam-
mable heat insulating panel (asbestos panel) with the thickness of at least 5 mm, located 25 mm from
the protected flammable material (flammable insulation). A shielding panel or protective screen (on the
protected object) must exceed the outline of the boilers (incl. flue gas ducts) at each side by at least 150
mm and the top surface of the boiler by at least 300 mm. A shielding panel or protective screen must
also be used to protect fixtures of flammable materials if the safe distance cannot be maintained (e.g. in
mobile units, huts, etc. - more details in ČSN 061008). The safety distance must also be maintained in

Operation and Maintenance Manual - GB
GB
www.atmos.cz GB-15
case of installation of fixtures near boilers.
If boilers are located on a floor of flammable materials, they must be installed on a non-flammable,
heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening by at least
300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat insulation
pads you can use all materials of the A flammability class.
Tab. nr.1
Flammability classes of
building materials and
products
A - no flammability granite, sandstone, concrete, brick, ceramic tiles, mortar, fire-resist-
ant plastering, etc.
B - difficult flammability Akumin, Izomin, cemented fibreboard, Lignos, panels of basalt felt,
fibreglass panels, Novodur
C1- poor flammability hardwood (oak, beech), hardboard panels, plywood, Sirkolit, Wer-
zalit, hardened paper (Formica, Ecrona)
C2- medium flammability softwood (pine, larch, spruce), chipboard and cork panels, rubber
flooring (Industrial, Super)
C3- high flammability Fibreboard panels (Hobra, Sololak, Sololit), cellulose materials,
polyurethane, polystyrene, polyethylene, lightened PVC
WARNING - In circumstances leading to the danger of transient ingress of flammable gases or
vapours and during work that might result in a temporary risk of a fire or explosion (e.g. gluing
of linoleum, PVC, etc.) the boilers must be put out of operation in time before the occurrence
of the danger. No objects of flammable substances may be put on the burner and boiler in
a smaller distance than the safe distance from them (more - see ČSN EN 13501-1).
In short, do not put any items that could easily catch fire in the vicinity of the boiler.
